Hengmei Optoelectronics Co., Ltd. was established in 2014 and is engaged in the research and development, manufacturing of display screen materials such as polarizing films, optical functional films, and optical compensation films. Hengmei Optoelectronics has built and put into operation four polarizing film production lines through the construction of production bases in Kunshan, Fuzhou, etc., including two 2.6-meter ultra wide polarizing film production lines. The global market share of large-sized polarizing films over 65 inches has reached 30%.

In 2014, Hengmei Optoelectronics started building a 1.5-meter polarizing film production line in Kunshan, promoting the development of 55-65 inch LCD displays; In 2017, Hengmei Optoelectronics made a groundbreaking investment in building a 2.5-meter ultra wide production line, reducing the cost of televisions over 86 inches; In 2022, the 2.6-meter ultra wide polarizing film production line was successfully put into operation at the Hengmei Fuzhou factory, which can supply 116 inch interactive tablets for use; In 2024, Hengmei Optoelectronics started construction of a 3-meter ultra wide polarizing film project in Kunshan. After reaching production capacity, it will assist in the production of 130 inch ultra large screens and achieve a breakthrough of "zero" in the global ultra large screen industry.
